Hi Ramiro,
I would also suggest taking a look at the publication list to understand a bit
better what can be achieved using deal.II (and, hopefully, how to do it). Here,
for example, is some work done in vascular biomechanics, and the publication
list has several other references to FSI.
@phdthesis{2017_31,
author = {A. M. De Villiers},
title = {A patient-specific FSI model for vascular access in
haemodialysis},
school = {University of Cape Town},
year = {2017},
url = {http://hdl.handle.net/11427/24441}
}
Although I’m absolutely not an expert on the topic, I agree with Thomas that
Luca’s work on immersed methods might be of interest to you when it comes to
modelling the interaction between a highly deformable structure, such as a
valve, and the fluid that surrounds it.
Best,
Jean-Paul
